2 Claims.

This invention relates to liquid delivery apparatus and has more particular reference to a simple and novel means for attaching said delivery apparatus to a container or barrel.

An important object of the invention is the provision of a thimble and intermediate connector adapted to act upon sealing means to effeet a closure against the escape of pressure fluid and to prevent any escape of liquid from the container incident to the insertion of the delivery means.

Another important object of the invention is the provision of attaching means for liquid delivery apparatus whereby an attaching thimble and intermediate connector are held in locking relation against axial rotation and adapted to slide within each other longitudinally with respect to their axis.

A further object of the invention is the provision of attaching means of the above character adapted to be held in locked relationship and in operative position by an intermediate connector whereby axial rotation of said intermediate connector serves to draw both thimble and intermediate connector together to act upon a yieldable gasket or sealing member.

Another important object of the invention is the provision of an attaching means which will permit of simple assembly and disassembly of the parts when effecting an installation or removal of the delivery apparatus to the barrel or container.

.On the drawing,

Figure l is a side elevation showing the dispensing tube attached to the upper end of a container or barrel a portion of which is shown in section;

Fig. 2 is a sectional view taken substantially on the line 2-2 of Fig. 1 showing the attaching means in secured relation and approximately full size;

Fig. 3 is a view similar to Fig. 2 but with the parts shown in an unattached position; and

Fig. 4 is a sectional view taken substantially on the line l4 of Fig. 2 showing the key and keyway connection between the thimble and intermediate connection.

Referring to the drawing, reference character it indicates generally a portion of a metal container or barrel having in its top wall l I, an opening i2 which normally is closed by a suitable closure I3 and which is adapted to be forced into the interior of the barrel when it is desired to discharge the contents thereof in controlled quantities.

The delivery apparatus comprises a fixture l4 having communication with a pressure fluid supply mechanism, as a pump, indicated at l5 at its upper end, while at its lower end the fixture has communication with an air delivery tube It within which is a liquid supply tube H. A faucet 68 of any desired type is connected in a suitable manner with a lateral extension of the fixture Hi intermediate the upper and lower ends thereof.

Rigidly secured to the top wall II of the barrel l3 and surrounding the delivery pipe I6 is a bushing l9 preferably circular in shapeand provided with spaced inner and outer vertically disposed circumferential flanges 2| and 23 respectively, adapted to form boundaries for an annular well or recess 24. The flanges are formed integral with a transverse portion 25 at the lower end of the bushing l9 which conforms to and lies upon the top Wall of the barrel where it is welded or otherwise secured at 26.

The flange 2| terminates at its upper end in a smooth horizontal surface 21 somewhat above the upper end of the flange 23 which is provided with an annular and sloping ledge 28 having a pair of diametrically opposed openings 29 extending through the ledge 28 to provide longitudinal passage for a thimble member 3|.

The thimble member 3| is circumferential in shape and is provided with a'longitudinally disposed wall 32 somewhat larger in diameter than.

upwardly fromithepr'ojections for a portion of its length, further extension fromthis point result: ing in a diametrically reduced, tubular portion 35 provided with a pluralityof diametrically opposed keys or ribs 36 on its inner circumference and with screw threads 31 along the surface of its outer circumference. g

The connector 39 comprises an enlarged circular connector portion 4| of greater length than the portion 35, having keyways or axial grooves 42 on its outer surface in registration with and.

for the reception of the keyway extension or ribs 36.

Extending below the portion 4| is a reduced neck portion 43 adapted to embrace the delivery tube It and providing at the same time a shoulder 44 for frictionally engaging and compressing a yieldable gasket 45 interposed between the shoulder 44 and the upper surface of the ledge 28 to preclude any leakage of the pressure fluid supply from the container or barrel beyond this point.

The enlarged portion 4| of the intermediate connector 39 terminates at its upper end in a horizontal shoulder portion 46 from where a reduced tubular portion 41 extends upwardly to provide at its uppermost end a bearing portion 48 for the delivery pipe Hi. The bearing portion 48 is threaded on its exterior to make provision for a packing gland means 49 which comprises a packing retainer member 5| threaded to the portion 48, a packing gland nut 52 in threaded engagement with the member 5| and rotatably secured to a bearing member 53 surrounding the pipe l6, and a yieldable gasket 54 in a sealing position between the bearing portions 48 and 53 to insure against any leakage about the upper portionof the delivery pipe Hi.

It will be noted that the thimble 3| and intermediate connector 39 are adapted to be fixed to each other with respect to their axial alinement yet are movable longitudinally with respect to their axis by virtue of their key and keyway connection, and in order to firmly secure the thimble and intermediate connector in a sealing or operative position as shown in Fig. 2, a coupling nut member 56 is provided.

The coupling nut comprises a cylindrical portion 51 surrounding the thimble 3| and adapted to rest or bear against the upper surface 21 of the-bushing l9, a reduced portion 58 provided with an internal thread 59 for engagement with the thread 31 of the upper portion of the thimble, and a reduced cylindrical extension 6| loosely I embracing the intermediate connector and provided along its entire length thereof with a plurality of wings 62 adapted to be grasped and by an operation to effect rotationof the coupling nut thereby drawing the thimble and intermediate connector together into a sealing position.

It is believed that a description of the operation of the device will serve to more clearly understand the merits of the invention. 7

, In the operation of the device, the entire structure may be placed over the bushing with the de livery tube in the position shown in Fig. 3. The coupling nut 58 carrying the thimble 3| and intermediate connector 39 in an attached but separated condition is grasped and placed over the bushing permitting the portion 33 to pass through the openings 29 and then given a quarter turn, causing the parts to take the position shown in Fig. 3.

The coupling nut is then turned upon its threads causing the thimble to be drawn upwards since it is held from rotating about its axis by'the key and keyway connection, until the portion 33 contacts'the under side'of the ledge 28. Continued rotation of the coupling nut now acts upon the intermediate connector to force it downwardly,- wedging the yieldable gasket 45 between the shoulder 44 and the upper surface of the ledge 28 and between the inner and outer surfaces of wall 32 and the bearing portion 43, respectively, until the coupling nut contacts the surface 21 of the fixed bushing l9 after which further movement is prevented. In this manner a seal is provided against the discharge of the liquid along the outer surface of the pipe l6 during such time when the end of the latter has forced the closure inwardly and permitted the tube to be pushed into the container, whereupon the device is ready for use.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

We claim:

1. An apparatus for delivering. liquid from a container by forcing a pressure fluid through a pipe into the container, comprising a sealing means adapted to prevent the discharge of fluid from the container on the outside of the pressure fluid supply pipe, a connector having a shoulder adapted to engage the sealing means, a bushing secured to the container and having a seating portion for said sealing means, an

actuating element for the connector having a shoulder in engagement with the same, said actuating element being rotatable and longitudinally movable relatively to the container, and a thimble interposed between the connector and the actuating element and being in screw threaded engagement with said actuating element, said thimble having means for looking it against the seat portion of said bushing, the actuating ele ment being provided with an end portion adapted to engageagainst said bushing to impart rigidity to the apparatus, whereby upon rotation of said actuating means after looking engagement between the thimble and the seat portion has been established, the first named shoulder of said connector is forcibly pressed against the sealing means until prevented from further movement by contact of said actuating element with said bushing.

2. In an apparatus for delivering liquid from a container having a supply pipe, and a carrier element for said supply pipe; a bushing secured to said container and having a pair of annular upstanding flanges thereon, a thimble mounted for sliding movement only on said carrier and adapted to engage one of said flanges of said bushing, and an actuating element surrounding said carrier and adapted to engage a shoulder thereon, said actuating element being mounted for screw threaded engagement with said thimble and having an annular end portion for contacting the other of said flanges of said bushing to positively limitrelative movement in one direction between said carrier, bushing, thimble and actuating element.
